IRON ALLOY.

No Drawing.

To all whom it may concern:

Be it known that I, HENRY K. SANDELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Iron Alloys, of which the following is a specification.

My invention relates to certain metallic alloys and more particularly to an alloy which, when it is mixed with iron, produces a new metal especially useful in the arts as a substitute for brass and the like low melting-point alloys, in common use for the production of intricate castings.

To prepare my new alloy the following procedure is adopted:

45 parts by weight of shot nickel is melted in an electric furnace with the addition of about 5 parts by weight of manganese. To this mixture there is added 50 parts by weight of copper.

The resultant alloy is foundto be capable of entering into solution in iron in all proportions. I. find that a mixture of 50% iron and 50% alloy produced as above described, forms a white metal of good tensile strength Specification of Letters Patent.

Patented Sept. 1'7, 1918.

Application filed June 18, 1917. Serial No. 175,368.

comparable with that of iron, very much softer than cast iron, and machining much more readily, capable of taking a high polish and maintaining its bright surface on exposure to the elements and of a very high degree of ductility, relatively speaking, as evidenced by the fact'that a one-quarter inchcast rod may be bent through an angle'of 45 over the corner of an ordinary Vise beparts by weight of copper, parts by Weightof iron, and a relatively small proportion of manganese.
